EXTENSION-TABLE.

- Application filed August 11,

To all whom it may concern:

Be it known that I, MAX VVURM, a citizen of the United States, residing 'in Brooklyn, in the county of Kings, State of New York,

have invented certain new and useful Improvements in Extension-Tables, of which the following is a specification.

My invention relates to extension tables to which one or more adjustable folding fillers or extension leaves are adjustably attached as a permanent part thereof and which are concealed within the table when folded and placed out of use, and the principal objects of 'the invention are to rovide a folding filler that may be operated in a comparatively shallow space beneath the level of the table-top members and which maybe easily adjusted into folded and un-folded position and securely locked in either of said positions, and which may also be readily attached to the ordinary construction of extension table as found on the market, with-- out requiring any especial alteration of the same.

With these and other objects in view my invention consists'in the various noveland peculiar arrangements and combinations of the several different parts of the apparatus, all as hereinafter fully set forth and then pointed out in the claims. I have illustrated .a type of my invention in the accompanying drawings, forming part of this specification, and wherein;

V Figure 1, is a central vertical sectional view of my improved table, the plane of the section being at right-angles to the abutting edges of the table-top members, and the three folding fillers are shown as folded beneath the table top, out of use. Fig. 2, is a top plan'view of the table with the table-top members slid into open position and showing the folded fillers'beneath and ready to be unfolded and brought up into place for use, as indicated in Fig. 4. Fig. 3, is a similar view to F ig. 1, but with the central one of the folding fillers adjusted in position of use between the table-top members and with the pedestal broken away. ig. 4, is a top planview of the table with the three folding.

-fillers adjusted into position of use between 'the members of thetable-top. Fig. 5, is a cross-secti0nal viewof the upper structure,

tion of the adjacent arrow. Fig. 6, is likewise a cross-sectlonal view of the upper structure, the plane of the section being indicated by line 6-6, in Fig. 2, and looking in the direction of the adjacent arrow; Figs. 7 and 8, are similar cross-sectional views, the

planes of the sections being indicated, re-

spectively, by lines 77, Fig. 2, andlines 88, Fig. 4;, Fig. 9, is a vertical sectional view of the central folding filler .shown'as about midway of its range of swinging movement.

Referring to the drawings, in whichlike numbers of reference .designate'.like parts throughout, 1 is a .pedestal which is shown as tin-divided, though of course an ordinary divided pedestal may be used, if desired, and

2, is the bridge or pedestal-cap which is held in fixed relation to the pedestal and carries at opposite ends the fixed guides or bars 3 and 4, respectively, upon the respective sides of which are slidably mounted the horizon tally moving slides 5 and 6, and 7 and 8. To the inner slides 6 and 8, are secured one" of the top-members 9, the other top-member 10, being secured to the outer slides 5 and 7,

respectively. The 'innerand abutting edges of the table top members 9 and 10, are .pro vided with. dowel pins and holes 11 and 12, respectively, which cooperate with each other to hold, the edges level and prevent sagging at the joint when the two members are placed together, as shown in Fig. 1. g i

A horizontally arranged spindle or a'xle 13, ismounted just below the under-side of the top members in suitably spaced longitudinally extending uprights'or brackets 14 and 15, respectively, which are secured upon the bridge 2, near the edges thereof, so that the spindle is disposed in the direction in which the top members slide. These brack- "brackets and extend beyond. each a distance greater than the width of the folding fillers or leaves 1718, and 1718, respectively, which are swung from the respective ends of the spindle. 'As the fillers just referred corresponding with corresponding reference numerals havthe case may be, and this lends support to the joint between these parts, as shown in in a prime mark annexed. The folding filler 1718, is composed of two sections 1 and-18, which are hinged together trans-' versely at a point near. the center, of length of the completefiller, by means of a substantial hinge 19, ofwell known construction and which I prefer to usein order to give a firm bearing to the hinge joint when the two sections are un-folded into the same plane in the position of use. side of the filler section 17, is secured a plate 20, having perforated lugs 21 and 22, through which thespindle 13, loosely passes and in this way the folding filler is mounted to swing on the spindle-on the over-hanging end thereof and eccentric to the hinge-joint.

Upon the ends of the spindle are secured stops 23 and 23, respectively, for limiting the lateral sliding movement of the fillers on thespindle,

to facilitate adjusting them into position of use anddisuse. These fillers are provided on their respective edges with dowel-pins 24, and holes 25, which cooperate with cor.- responding. parts on the abutting edges of the top members or the adjacent-filler, as

Fig. 4. Further support is given the filler when in position ofuse, bymeans of a turnbar 26, which is pivoted at 27, to an upextending projection '28, on the d 6. This wardly bridge piece 2. See Figs. 5 an turn-bar alsoserves to lock the folded filler in position of and .6, wherein it is shown as turned crosswise and projecting over By turning the bar 26, a quarter of a circle from the position shown in Fig. 2, the folded filler is un-locked ready to be swung up into unfolded position. Beneath the folding filler 17-18,'is placed check the downward movement ofthe free ends of the folded filler, as shown in Figs. 2 and 6. Except for this stop 29, the space beneath the filler is un-obstructed, so that the hinged end of the folded filler has an open space to swing through when turned on its eccentric axis on the spindle. provided a simple construction which in no way disfigures the ordinary table structure. The upright in which the spindle 13, is mounted is shown'as made in one piece with the extension 28, on which the turn-bar 26, is placed and this single piece is secured to the in Fig. 2.

On the under-side of the folding filler 17-48, are fixed pins 31 and '32, which engage with pins 33 and 34, respectively,

'To the underarranged a third one composed the fillers being permitted to have a certain amount of lateral movement disuse, as. shown in Figs. 2 Y

See Figs. 2 and .6. When the filler is un-folded into the Plane of the table top members, the drawing out of such members will cause the-pins on the slides to engage the pins on the filler and-carry the latter along with the slide.

It will be understood that the several parts in the drawings, marked 17 to 34, inelusive, are duplicates of the respective parts marked 17 to 34 inclusive,

31 and 32f, on the fillerand which have'been hereinabove described, so that it is not necessary to again describe said parts bearing the prime mark.

Between the two fillers just described, is

tions 36 and 37 which are secured together transversely by means this filler is located above the bridge and the pedestal, I provide means whereby the hinged end of on a very short radius inorder' to accommodate itself to the shallow confines of this part ofv the table. This I accomplish by causing the eccentric axis ofmotion to rise of two sec of a hinge 38. As

the filler is caused to swing as I and .fall in the swinging operatlon of th v filler. In this arrangement, the distance or radius between the hinge-axis and the eccentric axis on which the 'folded'filler swings, is much shorter than in the other two folding fillershereinabove described. In the construction shown, the eccentric arbor or axle 39, is mounted on-the under side of the section 36 of the filler, transversely thereof, by means of a bracket 40, having perforated ears 41 and 42, through which the arbor I passes. See Fig. 3. the arbor39, pass throughthe arms 43 and are pivoted at 45 and 46, respectively, to the extension 28, on the bridge piece 2. SeeFigs. 2, 3, 7, and 8. The ends of the arbor 39, project beyond the outer faces of the arms of the swinging yoke and when the 'filler is in unfolded position of use, the said endsrest in notches 47 and'48, respectively, which are formed in the brackets 14 and-#15. See Figs. 1, 2 and 8.- This serves to support the filler in itsextended position and prevent its sag- 'ng. When the filler is folded-the ends of the arbor likewise take into the notches 47 and 48, and permit depressed below At the same time the turn-bar 26, when lzacel cross-wise acts to support the section 3 o firmly held in extendedtain itself level with the top members. sections 36and 37, of the central filler are provided on their edges with dowel-pins 50 and holes 51, respectively, for cooperating with the corresponding parts on the adposition to main- The respective ends of The joining filler and top memben' See Figs. 2 and 3. These dowel-pins also serve to sustain the filler in secure position when placed between the top members, as shown in Fig. 3, or4between the end fillers, as shown in 1g. The central filler is placed in position of 'use by moving the turn-bars 26, into open the folded sections to clear the bridge and to be turned over in the shallow space above the bridge' When swung into upright po sition, the sectionsare' opened out and placed dicated in Fig.. 3, so that the table is eX- tended a distance equal filler. If a greater extension of the table is required, the end fillers may be placed in position by sliding back the top members and uncovering the fillers, whereupon they may be released and swung upwardly and unfolded across the slides and the top memberspushed against them, as shown in Fig. 4, thereby extending the table the distance of the aggregate Width of the three fillers. Before the fillers are unfolded across the slides, the turn-bars 26, are set at rightangles to the length of the fillers and when the latter are unfolded one section thereof is supported thereby,

as shown in Figs. 5and 8, :while the other section is supported by the spindle 13. Vhen the fillers at the respectivesides of the central one are unfolded into horizontal position and the parts slid together, the edges of the side fillers abut the edges of the central filler and this brings the side fillers directly over the uprights 14, 15, and 28, 28, which then serve to firmly support said fillers in horizontal 'position. To remove the fillers from position of use and store them in folded position beneath the top members, the latter are drawn apart and this movement first slides the members out of contact with the adjacent fillers so as to release the cooperating dowel pins between said parts. Then the continued movement of said members, causes the pins 33 and 34, on the slides 6 and, 8, respectively, to engage the pins 31 and 32, on the .under side of the filler 17-18, and to drag the latter sidewise so as to release the dowel-pins between the same and thecentral-filler. The pins 31' and 32, on the filler 1718, are likewise engaged by the pins 33 and 3-1, on the respective slides 5 and 7 and this serves to move this filler laterally and disengage the across the slides and then the top' members may be slid against the filler, as in-' to the width of the dowel pins between the same and the centralfiller.

apart in substantially the manner shown in This movement-spaces the fillers Fig. 2, whereupon they may be folded up 'and swung downwardly into the positions shown in Fig. 2, and then locked, after which the top-members may be pushed together and the fillers stored pins between the slides and the fillers there is sufiicient lost motion between them to causethe top-members to space themselves apart before engaging the fillers to draw them away,-so that the drawing-out movement of the top-members serves to automagically space them and the fillers from eac away and concealed, as shown in Fig. 1. In arranging the .80 other and permit the fillers to clear the different parts in folding them and swing ing them into their lowermost positions.

It will be seen that by virtue of my novel construction, I am enabled .to operate the folding fillers in a very shallow space and particularly the central filler which is located over the bridge, and that my improvements may be readily applied to many forms ,of ordinary tables as found on the market,

without making practically any alteration therein. Moreover, there is no depending or tant advantage in this class of devices.

I wish to be understood as not limiting my invention to the particular construction of the various parts thereof as herewith shown,

as it is evident that various modifications may be made in the same,

without departing from the spirit of my invention.
